The main objective of this work was to study the electrochemical behavior of Ni-Ti alloy immersed in two types of artificial saliva: neutral saliva (Ringer's solution, pH = 7.4) and acidic saliva (Fusayama solution pH ∼ 2.3). This study was conducted by the application of various electrochemical methods [monitoring of the corrosion potential over time; E = f(t), polarization curves; j = f(E), and electrochemical impedance spectroscopy EIS]. The overall results showed that the acidification of the saliva and/or the increase of its temperature causes the ignition of the corrosion phenomena of the Ni-Ti alloy. Indeed, the corrosion rate increases significantly with increasing temperature and the decreasing of the pH medium. © 2016 Wiley Periodicals, Inc.

Biodegradation and Thermomechanical Behavior of 3D-Printed PLA Scaffolds Under Static and Stirring Biomimetic Conditions.

Department of Mechanical Engineering and Aeronautics, University of Patras, 26504 Patras, Greece.
3D-printed biomedical polylactic acid (PLA) scaffolds were developed, and their biodegradation, as well as their thermomechanical behavior, were studied in a relevant in vitro environment. The scaffold's biodegradability profile has been monitored after immersion in a cell culture medium that contains components of blood and body fluids. Two types of biodegradation experiments were performed-a standard static one and an adapted stirring one, mimicking the body fluids' flow, respectively-to achieve a comparative investigation.

Honey has a rich history of treating gastrointestinal diseases due to its diverse bioactive compounds. This study evaluated the protective effects of select Iranian honeys against cold water immersion stress (CWIS)-induced ulcers in rats. Forty male Wistar rats (250-280 g) were randomly assigned to eight groups ( = 5): control, CWIS, and groups treated with strong (eucalyptus, Annaab, and Jangale) and weak honeys (Chand Giah, Sumaq, Gaz) + CWIS.

This study explored the use of virtual reality (VR) in disaster preparedness education, focusing on VR scenarios, disaster types, and user interactivity to identify gaps in existing research. A scoping review methodology, based on the Arksey and O'Malley framework and Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Reviews (PRISMA-ScR) guidelines, was used, and the protocols were registered in the UMIN Clinical Trials Registry (UMIN000052800). The review included PubMed, CINAHL, the Cochrane Central Register of Controlled Trials in the Cochrane Library, and Ichushi-Web of the Japan Medical Abstract Society, with data up to January 31, 2024.

Using the self-consistent field approach, we studied the salt-controlled vertical segregation of mixed polymer brushes immersed into a selective solvent. We considered brushes containing two types of chains: polyelectrolyte (charged) chains and neutral chains. The hydrophobicity of both types of chains is characterized by the Flory-Huggins parameters χC and χN, respectively.
